DETAILED DESCRIPTION

The disclosed technology is directed to infrastructure construction and management. The current industry practice in infrastructure construction and buildout progressing and quality integrity is based on manual processing supported by independent systems with massive data entries. Moreover, the current practice lacks an integrated systems that can capture the whole process of construction from design, supplies, construction asset, construction tools, material, workforce, and quality controls. In contrast, the present disclosure introduce an end-to-end operating model for an integrated digital twin, Infrastructure Construction Digital Integrated Twin (ICDigIT), the serves to bridge the construction and operation of an industrial facility. For example, the ICDIT encompasses the complete cycle of the facility construction and operation, including, Engineering Design and Simulation, Procurement and Logistics, Construction and Handover, and Operation and maintenance. The supply chain management attribute across these four main segments is included.

The Infrastructure Construction Digital Integrated Twin (ICDIT) is based on interaction and interplay between exemplary components in designing and construction of a plant facility. These components encompass various aspects of data sensing, collection, exchange, and computing. In one use case example, implementations of ICDIT can track asset build/assembly during construction. Here, real-time information such as imagery from the construction site, data from traffic scanning of asset movements, data from sensor networks at the construction site may be leveraged to determine construction progress, inventory tracking, etc. In another use case example, a controller provides route mapping and localization services throughout the plant for which guided escape routes maybe improvised in hazardous events such as gas leaks or fire outbreaks. In other words, during an emergency, a wearable device on a crew member may be equipped with real-time location and situation awareness information to navigate the crew member through the thick of the emergency to safety.

FIGS. 1A to 1C illustrate examples of various aspects of an Infrastructure Construction Digital Integrated Twin (ICDIT). As illustrated by diagram 100, the ICDIT encompasses complete cycles of the facility construction and operation, including construction projects 102 running the project digital twin 103F and operation facility 104 running the operations digital twin 103G. The project digital twin may include engineering design and simulation module 103A, procurement and logistics module 103B, and construction and handover module 103C. The operations digital twin 103G may include operations and maintenance module 103D. The supply chain management module 103E may extend over both twins.

The ICDIT 100 is based on interaction/interplay between the components in designing and construction of plant facility, which, as illustrated by diagram 110, can include superimposed multidimensional data acquisitions, processing, correlation, and visualization. The multidimensional aspects can include 3D, 4D (time), 5D (Cost), 6D (Efficiency), up to 7D (Operate & Maintain). These components, as outlined below, together form the digital twin for the facility construction. The visualization Hub 112 interacts with process simulation module 111A, electric instrument module 111B. structure stability analysis module 111C, material take-off 111D, scheduling and quality 111E, process and instrumentation design PFD 111F, mechanical design module 111G, piping module 111H, equipment sizing module 111I, cost estimation module 111J, construction sequence module 111K. As illustrated, the visualization hub 112 engages data management 113A, drawing generation 113B, clash detection/standards attributes 113C, and construction management 113D. The visualization hub 112 further engages design review 114A, RFT/ID process 114B, hand over document 114C, and handshake processes 114D.

The ICDIT 100 incorporates data sensing, collection, exchange, and computing over high speed network exemplified by local network traffic concentrator LNTC 123, as illustrated by diagram 120 of FIG. 1C. In more detail, The ICDIT 100 is based on interaction, interplay of hierarchical building blocks including work flow generator interface system (WGIS) 121A, real time visualization progression RTVP 121B, construction project safety monitoring system (CPSMS) 121C, central time distributed system (CTDS) 121D, central network traffic concentrator (CNTC) 122A, safety and quality monitoring system (SQMS) 122B. Through high speed network managed by local network traffic concentrator (LNTC) 123, multipurpose sensor network (MSN) 124A, people based sensor (PBS) 124B, traffic scanner system (TSS) 124C, event based autonomous sensors (EBAS) 124D, fixed asset based sensor (FABS) 124E, dynamic asset based sensor (DABS) 124F, and mobile asset sensor (MAS) 124G jointly provide location and situation awareness for multidimensional visualization including 3D, 4D (time), 5D (Cost), 6D (Efficiency), up to 7D (Operate & Maintain).

The local network traffic concentrator (LNTC) 123 can connect to wired and wireless field devices and networks. The LNTC 123 includes computing and data storage capability. The LNTC can process all collected data and produce reporting and new database that can be used by other 3^(rd) party applications for Artificial Intelligence (AI) and Machine learning application. The LNTC 123 includes software interface capabilities (Application Programming Interface or API) to connect with other databases locally or in wide area network. The LNTC 123 can translate captured images for the dynamic asset and establish mapping to the facility build out plan, timelines, asset inventory, and produce a predictive model on anticipated progress, asset consumption. In some cases, the LNTC 123 can capture all the data from the operator within the facility, can capture data from mobile, can translate captured images for the dynamic asset and detect metrological hazards and/or unsafe conditions, can capture all the data from EBAS 124D, and can communicate commands to SQMS 122B.

In comparison, the CTDS 122A is based on fault tolerant network time protocol (NTP) clock synchronization with a direct GPS feed. The CTDS 122A has internetworking capability to interface all the field devices. The CTDS 122A can synchronize all field devices with the same time stamp point.

The workflow generator interface system (WGIS) 121A can develop, add, delete, and modify workflows for asset use and resource management. For example, the interface workflow may merge seamlessly with communication systems such as email, wired phone, mobile phone, and other web-interface communication systems.

The real time visualization progression (RTVP) 121B can display real-time build out activities program. For example, the RTVP 121B may superimpose build out 3D image with the real-time progress feed. The RTVP 121B may provide dashboard and reporting capabilities on both construction progress and safety behavior metrics. The RTVP 121B may have the capability to detect schedule and geometric mismatch between the real-time captured 3D module and the 3D planned design. The RTVP 121B may include software interface capabilities (Application Programming Interface, e.g., API) to connect with other databases locally or in wide area network. The RTVP 121B may have the capability to communicate with DABS 124F and/or EBAS 124D to request camera movement and robot/drone dispatch.

The safety and quality monitoring system (SQMS) 122B can be embodied as a construction project quality monitoring system (CPQMS) and a construction project safety monitoring system (CPSMS). In case of the CPQMS, SQMS 122B can project construction progress visualization through the creation of 3D models from videos and imagery taken either by ground CCTV systems or aerial photogrammetry such as from drones. The data from the 3D models are correlated with asset construction progress from resource management. This can include 2D engineering tools, materials management, project controls, scheduling systems, and video and analytics systems. The SQMS 122B can provide 3D scanning to capture the construction status and verify it against the design basis in the 3D model to ensure that future construction and operation will proceed smoothly and identify any quality issues as early as possible. The SQMS 122B can provide true 3D model from a circular aperture or multiple single aperture, with high definition resolution (mm to km), provides active and passive 3D modeling, and allows identification and tagging for industrial equipment. The SQMS may utilize the available data from 3D models, 2D engineering tools, materials management, project controls, and scheduling systems, to ensure that accurate and timely decisions can be made on the most updated information needed for optimized construction planning and execution.

In the case of the CPSMS, the SQMS 122B can include monitoring, detection and notification of workers health, unsafe behaviors and unsafe conditions using data from the available work management systems including access control, health monitoring systems, and meteorological monitoring systems. The SQMS 122B involves acquiring, processing and analysis of CCTV systems video and imagery output. The SQMS provides real-time notifications when a potential safety violation is occurring that is related to workers health, unsafe behaviors and unsafe conditions. The SQMS 122B gathers and integrates data from worker health conditions, meteorological conditions and related site safety requirements. The SQMS 122B can includes worker identification by, for example, providing facial identification (or other biometrics), regulating access authorization to restricted areas, regulating general access authorization whether to allow or deny identified individuals, and creating space safety zones. The SQMS 122B can further monitor worker health conditions including, for example, heat and cold stress conditions, slip and fall incidents, fatigue conditions, man down incidents, overexertion conditions, and fit to drive status, track location, monitor proximity alerts, create time safety limits (e.g., flagging workers not following minimum resting requirements), and link requirements with meteorological conditions. The SQMS 122B can additionally assist to enforce personal protective equipment (PPE) by, for example, defining PPE safety requirement zones, detecting, safety shoes, safety vests, safety harness at elevated platforms for instance, eye protection, helmet and hard hat, and ear plugs. The SQMS 122B may further enforce early detection of other workplace surrounding hazards including, for example, falling hazards from elevated platforms or shop-floor surfaces such as slippery surfaces, trip hazards, clutter, leaks, standing water, working at heights, and fall protection gear. Such workplace surrounding hazards may additionally include: electrical overhead travelling crane, and mobile equipment hazards and electrical hazards. The SQMS 122B may additionally identify when a worker shows signs of fatigue; identify blocked fire exits, spills, and over-stacking/blocked sprinkler heads; identify prohibited usage of mobile inside process areas; use tagging to track chemicals, and how long they have been kept, notify when hazardous chemicals are pulled from storage; notify and tack how long an employee enters a confined space, repetitive motion alert, improper lifting form alert; and identify unauthorized vehicles accessing prohibited areas.

The multipurpose sensor network (MSN) 124A includes integrated sensors that have direct and indirect contact sensing capabilities covering people, fixed asset (such as completed buildings), dynamic asset (such as drillings), mobile asset (such as vehicles) and autonomous sensors. The MSN 124A may communicate via wire, wirelessly, or both. The MSN 124A is capable of operating at various temperature and weather conditions (e.g., rainy or dusty weather). The MSN 124A can additionally trigger visual and/or audible notification. In more detail, the sensors can has computing and data storage capability in addition to retaining time and location. The sensors can also be personalized to an operator or worker specific setting.

The people based sensor (PBS) 124B may include durable sensor and non-reusable sensor. An example of a durable sensor can be an equipment supported by long last power source, digitally operated with contact sensors that has the ability to be personalized and collect human essential health signs, location, movement, direction, and posture. Human essential health signs sensor may be based on direct sensor contact with the human body, hand wrest, chest, and or legs. It can be embedded as part of a wearable uniform and or similar to other personal protective equipment (Hats, Wearable clothes, and portable with connection on demand). Location aware sensor has the ability to keep track of the location based on, for example, global positioning system (GPS) or radio-frequency identification (RFID) positioning system. These sensor generally retain movement and direction and may relay the collected data. An example of a non-reusable sensor include a sensor made of synthetic material that that can be attached on human to a surface. While such sensors can be discarded, the non-reusable sensors support RFID technology and are readable by RFID scanning technology. For example, each may be associated with a unique 2D bar code that can be scanned by a camera device.

The fixed asset based sensor (FABS) 124E can report on location and trigger alarms upon unauthorized mobility. The dynamic asset based sensor (DABS) 124F can be equipped by video/optical sensor network that keep tracks of its progression. In some instances, the optical/video system will be based on high resolution (60 frame per second). The optical/video camera movement can be based on a control loop feed. The control feed input may be based on detection of a change in construction or predefined schedule. The optical/video system may be capable of wide-angle capturing (80 degrees) field of view, super-wide angle of 180 degrees or higher.

The mobile asset sensor (MAS) 124G may be equipped with a device to capture data on speed, engine health status, operating hours, outage time, parts replacement. The MAS 124G may be networked and location aware of the current position. In some instances, the MAS 124G has 360 sensing capability of other objects within 1 to 15 meters. In these instances, the MAS 124G may incorporate a control loop based on feedback input from other assets of approaching objects and trigger alarms to prevent direct contact with other objects.

The event based autonomous sensors (EBAS) 124D may be equipped by video/optical sensor network mounted on autonomous robotics and/or drones. In some cases, the optical/video system is based on high resolution (60 frame per second). In these cases, the EBAS movement can be based on a control loop feed with autonomous maneuver algorithm/AI. The control feed input is based on a request from PBS 124B, FABS 124E, DABS 124F or MAS 124G, predefined schedule or manual dispatch. The optical/video system may be capable of wide-angle capturing (80 degrees) field of view, super-wide angle of 180 degrees or higher.

The traffic scanner system (TSS) 124C can scan people, tools, and assets. In some cases, the TSS 124C include scanners that are positioned based on the build out structure pathways. In these cases, the scanners are connected to alarm and sound system that will be trigged by the object movements with corresponding sound or message. Each scanner may include local computing and data storage capabilities, can communicate wirelessly or in a wired manner, and can read data via RFID technology.

Implementations described in the present disclosure can provide seamless integration with plant automation systems of an industrial plant, enabling it to receive commands and respond to alarms and system alerts. As illustrated in FIG. 2A, an example of a Wireless, Wireless ISA, Long-Range Wide Area Network (LoRaWAN), and or 5^(th) Generation Wireless network architecture 200 can include wireless field instruments 202 (further including instruments 202A, 202B, 202C, 202D, 202E, 202F, 202G, and 202H that form a RF mesh network 203), and a Wireless gateway 204 on a plant control network 205 (e.g., through interface 205A that includes Ethernet). The plant control network 205 may operate a DCS (distributed control system) that emphasizes process-level operations, or a SCADA (supervisory control and data acquisition) that is event-driven and prioritizes data gathering (206). For example, A DCS delivers data to operators, and at the same time, a SCADA concentrates on the acquisition of that data. The Wireless gateway 204 may operate a gateway security manager 204A. The Wireless gateway 204A may include three main functions, namely, access point, radio, and manager, in one box serving only one particular area in the plant. As described in the present disclosure, the Wireless network is re-architected so that the “Radio” and “access point” are detached from the controller and managing software. The access point are distributed throughout the plant and are connected back to “one” controller serving the entire plant facility. The central controller does not only provide wireless connectivity management but also provided wireless power to access point. The process control instrumentation module includes a unified Wireless gateway function embedded in a central controller that interconnects and manages the field receptors.

Further referring to diagram 210 from FIG. 2B, the Wireless radio receptors (212A, 212B, 212C, 212D, 212E, 212F, 212G, and 212H) connect the remote field devices utilizing the 2.4 GHZ frequency band. The receptors are connected via physical medium back to the central controller 213A where the unified Wireless gateway is performed. The central controller 213A may include power supply 213B, management optimization and route mappings 213C, and PCS&DM (Process Control System and Data Monitoring) integration 213D. The Wireless gateway thus acts as a unified medium between the Wireless connected devices and the plant network using standard protocols such as Modbus or Profibus.

In some case, the controller comprises a unified Wireless gateway function interconnecting distributed wireless field transceiver using 802.11b/g/n/ac WLAN and converts the HART data to Modbus TCP for easy integration with the plant's control systems. The integration with plant's control systems can be made via an Ethernet port or the integrated controller through which it also connects the various WLAN client transceiver. The data collected from the field Wireless transceivers converted into Modbus TCP before transporting them on the plant's control systems. The controller is configurable and manageable via an embedded secure terminal connection for which detailed system diagnostics can also be made available. The field wireless transceiver is capable of connecting up to, for example, 250 Wireless field devices with the capability of an RF Link relay indication and the ability to measure the strength of the WLAN signal as an analog voltage. The field devices are automatically (dynamic assignment) assigned a Modbus ID to enable it to communicate with the master controller.

FIG. 2C shows an example of a Wireless gateway 220 to illustrate the unified Wireless controller components according to some implementations. The Wireless gateway 220 includes CPU (central processing unit) 221A, memory 221B, SSD (solid state storage device) 221C, management software 221D (which may include firmware), GPS/WiFi localization module 221E, OLE (object linking and embedding) for process control (OPC) 221F, remote diagnosis library 221G, Wireless HART, ISA, Long-Range Wide Area Network (LoRaWAN), and or 5th Generation Wireless controller 221H, SCADA/DCS interface 2211, plant network interface 221J, pattern recognition 221K, security module 221L, windsock input 221M, in addition to Modbus, RJ45, RS485, and OPC interface connectors. Here, windsocks are used to provide indication of wind speed and direction in analogue or digital representation. Windsocks may be used at petrochemical plant facilities where s risk of gaseous leakage or fire exist. In some windsock implementations, wind speed is indicated by the windsock's angle relative to the mounting pole; in low winds, the windsock droops; in high winds it flies horizontally. The speed of wind is estimated by highly visible orange and white stripes with each stripe adds up 3 knots to the estimated wind speed. For the present disclosure, a digital or analogue output windsock will be used to provide general wind speed and direction which will be used by the emergency route escape mapping procedures to determine the most accessible and safe exit for workers should an emergency occur.

Intelligence Instrumentation will provide the hat (helmet) with hardware/software based technical abilities to perform intelligent functions such as localization and guidance, expanded diagnostics based on pattern recognition and image analysis. Referring to FIG. 3A, an example of a helmet 300A can include a side-mounted intelligent device 301A while another example of a helmet 300B can include a side-mounted intelligence device 301B. The mounting location can be slightly above the ear location. As illustrated in FIG. 3B, an example of an assembly 310 can include a transceiver module 311 that includes antenna 311A and electronics 311B, a connector belt 312, and a terminal 313 that includes touch pad 313A with tactile control. In this example, the transceiver module 311 can be mounted on the outside of the helmet while the terminal 313 can be mounted on the inside of the helmet, for example, closer to the eye. The terminal 313 may also include projector-type of display to be mounted on, for example, towards the forehead region to project a visual display to the operator wearing the helmet. In some cases, the apparatus can support a helmet attached an ultrasound mobile emitter that can be used to scan the outer surface of pipes for potential corrosion or deformation. In these case, a portable hydrophones can be used to complement the function of the ultrasound emitter from the helmet. In some cases, the apparatus is able to read equipment tag and fetch information related to inventory, for example, supply and spare parts availability/compatibility.

FIG. 3C illustrates an example of a flow chart 320. The process starts (321) and a smart helmet (or hat) receives a safety incident alarm (322). In response, the PCT identified the area of the plant affected by the incident (323). In other words, the location of the incident determines whether the incident is in an area of hazard (324). If the determination is that the incident is not in a hazardous area, the process may proceed to acknowledge the alarm only (326). If the determination is that the incident is in a hazardous area, the process may proceed to acknowledge the alarm and second a position tag to a safety coordinator (325A), perform route calculation and map multiple exit routes (325B), and then starts navigation to guide the operator to safety (325C). The process may receive updated location from the operator's helmet and determine, in real time the whereabouts of the operator. Based on the location of the operator, the process may determine whether the operator is in a designated safe area (326). If the determination is yes, the process may transmit a success flag to alert manager 328 (327A). Otherwise, the process may transmit a fail flag to alert manager 328 (327B). The alert manager 328 may further communicate with the smart helmet.

In some implementations, the plant floor is divided into a number of cells or areas of coverage to facilitate adequate wireless connectivity and reliable integration to the process control systems. The areas are defined as part of a matrix with rows and columns so that each cell is addressable by its row and column identifier. As illustrated in FIG. 4A, an example of a plant floor 400 is divided 16 sixteen cells, in rows 1 to 4 and columns a to d. In this example, a receptor, which can operate on the Wireless protocol, is installed in each coverage area whereby the signal quality and propagation is ensured. The receptors are distributed throughout the plant floor and are connected to a central management controller for the whole plant facility. Further referring to FIGS. 4B to 4C, the placement of the receptors, as illustrated by plans 410 and 420, provide coverage for each area marked in hexagonal region, from area 1 (and sub-regions a to d), area 2 (from sub-regions a to d), area 3 (from sub-regions a to d), and area 4 (from sub-regions a to d). The hexagonal cells are grouped into respective areas, each can have its own connectivity or security profile.

Moreover, Audio Visual Alerting Systems (AVAS) is included in each area or region. The AVAS includes signal initiation, transmission, notification, and annunciation in the area designed and installed to meet the levels of performance. The AVAS components (loud speaker and alerting light) are used to complement the wireless Personal Protected Equipment and or Mobile Device communication. The AVAS stations are installed at least 1.5 Meter from the work area ground level of each Area or one or more Area to enable Operator to have a visual and can hear audio. AVAS provides visual alerting and visual systems such as changing color coding: Green=safe; Red=is danger; and flashing amber implies work is in progress). The AVAS Light and Audio stations which consist of amplifiers, junction enclosures, plugs and loudspeakers installed in Area are to be in compliance to area classification (industrial requirements Hazardous and standard building Management). AVAS will imply acoustic safety components in areas where ambient noise levels exceed 80 dBA. The AVAS include a multi-tone generator capable of generating different types of tones for different emergency conditions, such as, yelp, warble, siren, and steady tone.

The controller performs management and administration functions such as security management and controls including authentication and traffic optimization process for connected field devices. The controller also provides route mapping and localization services throughout the plant for which guided escape routes maybe improvised in hazardous events such as gas leaks or fire outbreaks. The controller is connected to all plant distributed receptors via physical mediums such as copper or fiber optic cabling to eliminate or minimize interference and provide robust and reliable system interconnectivity.

FIG. 4D illustrates a use case 430 of intelligent guidance for escape routes during emergency. As illustrated, a fire breaks out due to gas leak in an area close to the northern exit. An operator, for example, an employee operating on-site is notified of the emergency right away. Here, the controller may calculate an escape route based on real-time information from the various sensors at the plant. In this illustration, the computed escape is from area 3.a to area 3.b, then to area 2.b and to area 2d, and finally to area 2.d. The escape route can be computed to optimize the fastest route to a safety area, or the fastest time to an exit. In some cases, route computation is based on a static escape route plan which is defined as a result of the risk assessment (e.g., what if scenarios). Based on a risk event location, the route is displayed to the individual communication media (e.g., tablet, radio, phone that may be mounted on the individual's helmet) and the individual select the nearest route.

In some cases, the route can be computed based on captured sensor data (gas leak or fire) that is mapped to the facility floor plan. By superimposing the GPS location of the individual to the sensor data, an escape routed is identified and communicated to the person communication media (e.g., tablet, radio, phone that may be mounted on the individual's helmet) and the individual select the nearest route. As the individual progresses along the way, the routing information may be updated, for example, when the individual misses a turn, a better route emerges, or a new emergency occurs.

In various implementations, the escape route may be based on an algorithm with streams of input from multiple sensors. The sensor input can originate from body held sensing that could provide information about individual wearing the PPE (personal protective equipment) such as body temperature, heartbeat, perspiration rate etc. The sensor input can also come from plant instrumentation and control systems such as gas or chemical leaks, pressure spikes etc. The sensor input can also come from environmental such as wind speed and direction. The combined information is then augmented by localization information obtained from SSID (service set identifier) association throughout the plant for the most logical (e.g., fastest or closest) exit route that will insure the safety of the worker. Generally, it is preselected based on risk evaluation (e.g., in what if risk scenarios) or based on real-time sensor data correlation to the individual location, or a combination of both thus giving the individual the choice to select the suitable escape route.

Further referring to diagram 440 from FIG. 4E, an edge analytics platform 400 is provided to generate real-time routing information. Platform 400 includes network switch 441 providing connectivity to CCTV camera sensors 446, VMS (Video Management System) 442, analytics server 443, monitoring terminal 444, as well as user tablet 445. In this example, CCTV camera sensors monitor a plant facility to provide real time video streaming. Edge analytics can be derived based on the stream input using a stand-alone computing server 443 or utilizing VMS 442. The edge data analytics is correlated to key performance indicators (KPI) dashboard (e.g., user tablet 445) to achieve accurate worker identification and tracking, zero worker violations, and zero unsafe condition. The KPIs are achieved with high accuracy with no false negatives/positives which may introduce unreliability of the analytics. The edge detection capabilities are based on mapping the individual PPE profile to the actual facility area (zone or segment). The solution provides real-time notifications when a potential safety violation is occurring that is related to workers health, unsafe behaviors and unsafe conditions. The solution is capable of gathering and integrating data from worker health conditions, meteorological conditions and related site safety requirements, as outlined above with respect to FIGS. 1A to 1C.

FIG. 5 is a flow chart 500 illustrating an example of intelligent edge analytics based on some implementations. Multiple streams of sensor input can be collected at CCTV feed (504). These streams of input can include aerial scanning (501), mobile scanning (502), and fixed floor scanning (503). Here, the use of drone will provide aerial imaging (scanning) based on scheduled and unscheduled aerial trips. Based on the image feed from cameras and edge platform, video analytics can be generated (505). The video analytics are evaluated to determine a safety status (506) of the plant operation (507). If a safety violation is detected, a notification is generated (509) and the log file is updated (510). If no safety violation is detected, the process may continue with collecting and analyzing video feed (508). Based on the image feed from cameras and edge platform, 3D models of the constructed objects can be built (511). From this 3D model, a comparison can be made between the actual construction and the planned construction (518). Based on the comparison, a schedule (519) can be inspected to determine whether schedule variations exist (520). If no variations are detected, the process may continue with collecting and analyzing the video feed (521). If variations are detected, notifications are generated (522) and a log file is updated (523). From this 3D model, a comparison can be made between the actual construction and the designed project (512). Quality metrics can be inspected to determine whether there are quality violations (514). If no quality violations are detected, the process may continue with collecting and analyzing video feed (515). If quality violations are detected, a notification is generated (516) and the log file may be updated (517).

The term “real-time,” “real time,” “realtime,” “real (fast) time (RFT),” “near(ly) real-time (NRT),” “quasi real-time,” or similar terms (as understood by one of ordinary skill in the art), means that an action and a response are temporally proximate such that an individual perceives the action and the response occurring substantially simultaneously. For example, the time difference for a response to display (or for an initiation of a display) of data following the individual's action to access the data can be less than 1 millisecond (ms), less than 1 second (s), or less than 5 s. While the requested data need not be displayed (or initiated for display) instantaneously, it is displayed (or initiated for display) without any intentional delay, taking into account processing limitations of a described computing system and time required to, for example, gather, accurately measure, analyze, process, store, or transmit the data.

Certain features that are described in this specification in the context of separate implementations can also be implemented, in combination, in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations, separately, or in any sub-combination. Moreover, although previously described features can be described as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can, in some cases, be excised from the combination, and the claimed combination can be directed to a sub-combination or variation of a sub-combination.
